Feature 1Premium Materials: The detection pin is made of 304 stainless steel, having no electrolysis isolation design, and can be buried in soil for long term dynamic testing. 2Perfectly Sealed: The soil sensor has the design of epoxy resin vacuum potting, having better sealing performance, waterproof and easy to use. 3Easy to Use: The soil detector has a simple use, install and play, can be inserted into shallow or deep depth to detect the PH, moisture, conductivity of the soil. 4Excellent Performance: The soil moisture sensor has high accuracy, quick response, good interchangeability, probe insertion design ensures accurate measurement and reliable performance. 5Various Application: The soil moisture tester is less affected by the salt content of the soil and can be applied to all kinds of soil, having a variety of application.Item Type: Soil Moisture MeterMaterial: 304 Stainless Steel, Plastic, Rustproof Aluminum Zinc Alloy ElectrodeWeight: Approx. 344g/12.1ozWaterproof Grade: IP68Product Size: Approx. 133 x 60 x 45mm/5.2 x 2.4 x 1.8inCable Line: Approx. 5m/16.4ftBuilt In Sensor: Soil Temperature, Soil Moisture, PH, Nitrogen, Phosphorus and PotassiumType: RS485 (for Modbus)Supply Voltage: DC9-30VLoad Capacity: Current TypeOutput Impedance 250Voltage Type Output Impedance 1KMeasuring Range:Soil Moisture: 0 ~ 60% (Volume Moisture Content)Soil Temperature: -40 ~ 80PH: 3-10 PHNPK: 0-2000 mg/kgAccuracy:Soil Moisture: 3% (0-35% Measuring Range)5% (35%-60% Measurement Range)Soil Temperature: 0.5PH: 0.3PHNitrogen, Phosphorus and Potassium: 2%FSResolution:Soil Moisture: 0.1%Soil Temperature: 0.1PH: 0.1PHNitrogen, Phosphorus and Potassium: 1mg/kgWorking Environment: Soil Temperature -40 ~ 80; Soil Moisture 60%Application: Scientific Experiments, Water Saving Irrigation, Greenhouses, Flowers and Vegetables, Grassland and Pasture, Soil Rapid Measurement, Plant Culture, Sewage Treatment, Grain Storage and Measurement of Water Content and Temperature of Various Particles.Wiring Method:1. If the sensor is equipped with our instrument, connect the sensor directly to the corresponding interface on the instrument using the sensor cable.Description of the SensorforModbus:If you are connecting multiple sensors to a PLC, configuration or programmable acquisition, the standard ModBus-RTU(hex transmit and receive) is recommended.Standard ModBus-RTU1. Serial port formatData bit 8, stop bit 1, check bit none, baud rate 9600bps, serial debugging software set to hex send and receive, two communication interval of at least 1000ms, CRC in the manual for check bit, 2 bytes.2. Register addressYGC-SM Soil integrated sensor can integrate up to 8 soil elements, namely soil temperature, soil moisture, PH, and soil nitrogen, phosphorus and potassium content. Each element has its own register address.Troubleshooting:The sensor display value is incorrect when analog signal or RS485 output. The correct data cannot be obtained because the cable connection is faulty or the communication serial port is faulty. Check whether the cable connection is correct and secure, whether the serial port is occupied, and whether the serial port Settings are correct. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x SoilMoistureSensorNote1. Please check whether the package is intact, and check whether the product model is consistent with the selection; 2. Do not live wiring, wiring can be checked before power; 3. The sensor line length will affect the output signal of the product, do not change the product at will when using. 4, the sensor is a precision device, users in use, please do not disassemble, with sharp objects or corrosive liquid contact sensor surface, so as to avoid damage to the product; 5. When measuring, the probe must be fully inserted into the soil. 6. Avoid the high temperature caused by direct sunlight on the sensor, and pay attention to lightning protection when used in the field. 7. Do not violently bend or insert the probe, do not force or repeatedly pull the sensor wire, which will cause the root of the sensor wire to be disconnected and cannot be repaired. 8. Due to the existence of radio frequency electromagnetic radiation in the air, it is not appropriate to be electrified in the air for a long time. 9. When measuring the frozen soil layer, the moisture value will be low and
